Embodiment 1

[0051] see figure 1 and figure 2 , the shaft-mounted brake disc assembly for high-speed trains in the illustration is one of the preferred solutions of the present invention, specifically including a brake disc 1, a support disc 2, a first connection structure 3, a hub 4 and a second connection structure 5 , two sets of disc-shaped brake discs 1 are coaxially stacked on both sides of the support disc 2, the brake disc 1 and the support disc 2 are clamped and locked by the first connection structure 3, and the support disc 2 is also Ring disc shape, the heat dissipation structure is processed and set in the ring area where the disc surface on both sides of the support disc 2 overlaps with the friction disc, the disc surfaces on both sides of the brake disc 1 are processed flat, so that the stacked brake disc 1 and support disc 2 The heat dissipation structure forms the heat dissipation channel inside the brake disc. The inner ring of the support disc 2 is processed with a co...

Embodiment 2

[0065] see in conjunction Figure 9 and Figure 10 , the shaft-mounted brake disc assembly for high-speed trains in the illustration is a further preferred solution of Embodiment 1. In Embodiment 1, the brake disc 1 is an integral circular disc-shaped structure, and two groups of brake discs are stacked separately Locked on both sides of the support disc 2, the brake disc 1 can be disassembled from the support disc 2 for maintenance.

[0066] In the second embodiment, in order to further reduce the maintenance cost of the brake disc 1, the brake disc 1 is spliced ​​with several split brake discs 1' that are radially divided along the disc surface, such as Figure 10 In the semi-circular disc structure, each split brake disc 1' is stacked and locked with the support disc through an independent first connection structure 3, and the two split brake discs 1' are stacked and locked on the support disc 2, then splice to form a complete circular brake disc. In this way, when a cer...

Abstract

The invention discloses a shaft-mounted brake disc module for a high-speed train. The module comprises brake discs, a support disc and a disc hub; two sets of brake discs are provided, are coaxially laminated on the disc surfaces on the two sides of the support disc, and are clamped and locked with the support disc through first connecting structures; the brake discs are composite material brake discs with smooth disc surfaces on two sides; heat dissipating structures are arranged on the disc surfaces on the two sides of the support disc, and are laminated with the brake discs to form heat dissipating channels; and a connecting flange is arranged on an inner ring of the support disc, and is fixedly sleeved with the disc hub through a second connecting structure. Compared with a traditionaloverall brake disc, the module has the characteristics of simple structure, reliable connection, high-temperature resistance, convenience to maintain, light weight and good braking effect, reduces the energy consumption in operation and braking of the high-speed train, realizes application of a composite friction material to a high-speed train braking system, and greatly saves the high-speed train company operation and maintenance costs.

Description

technical field [0001] The invention belongs to high-speed train braking technology, in particular to a shaft-mounted brake disc assembly for high-speed trains. Background technique [0002] Brakes are the key components of high-speed trains, which are related to the safety of high-speed trains. Because of the complex and harsh working environment and inconvenient maintenance and replacement, brake products must have reliable braking, convenient maintenance and long service life. [0003] High-speed train brakes generally include the following two types: shaft-mounted brakes and disc brakes. Among them, shaft-mounted brakes are more common, that is, hydraulically driven friction plates squeeze and rub the brake disc fixed on the axle, and then brake the axle through friction. At present, the shaft-mounted brake discs used in high-speed trains are generally made of steel. , although it has the characteristics of high technology maturity, low cost, and wide applicable speed r...
